Ray Stevenson (Punisher: War Zone) talked to Empire about how he will play Volstagg the Valiant, one of the Warriors Three, in Marvel Studios’ Thor.

He tells the magazine they will be using a fat suit to make the actor bigger. “It’s fantastic. I’ve tried the suit on, and what they’ve done is kind of sex him up: he’s sort of slimmer but rounder,” said Stevenson.

He added that the character has “got every bit of that Falstaffian verve and vigour, and a bit of a beergut to suggest that enormous appetite, but he’s not the sort of Weeble-shaped figure he is in the comics. He’s Falstaff with muscles. I’ve got this amazing foam-injected undersuit that flexes with me. I can’t wait!”

Filming on the Kenneth Branagh-directed film will start in January for a May 20, 2011 release.
